Breastfeeding Advice



  • While breastfeeding, your health, your food choices, and how much rest you get can affect your milk supply.
  • Eat a variety of foods at regular mealtimes and have healthy snacks between meals to get an extra 500 to 800 calories a day while breastfeeding.
  • Drink plenty of liquids, avoid alcohol and smoking, and ask your healthcare provider about taking any medicines while you are breastfeeding.


You may have questions about how you will need to change your lifestyle while breastfeeding. You don't need to follow a lot of rules, but your health, your food choices, and how much rest you get can affect your milk supply. Here are a few things to keep in mind:

  • Follow the same kind of healthy diet that you followed when you were pregnant.

    You need an extra 500 to 800 calories a day while breastfeeding. Eat a variety of foods at regular mealtimes and have healthy snacks if you are hungry between meals. Eat more fresh fruits, vegetables, whole-grain breads and cereals, and nonfat dairy products. Be sure to get enough protein from meat, fish, poultry, and beans.

    If you are a vegetarian, you may need to increase the amount of vitamin B12 in your diet to make sure your baby gets enough. Talk to your healthcare provider about this.

  • In general, you can eat any foods.

    Babies are not allergic to breast milk, but things that you eat pass into your breast milk. If your baby reacts to something you ate, your baby may cry, cough, have a stuffy or runny nose, vomit, have diarrhea, or get a rash on cheeks or bottom.

    If a certain food or drink seems to upset your baby, avoid that food or drink for a couple of weeks before you try it again. The most common foods that can cause allergic symptoms in a breastfed baby are cow's milk and other dairy products, peanuts, tree nuts, wheat, eggs, fish, shellfish, and soy.

    If you think your baby is having a reaction to certain foods, talk to your healthcare provider. Do not eliminate a major food group, such as dairy or wheat products, from your diet unless your provider or dietitian agrees. They can suggest foods that will give you the same nutrients as the foods that bother your baby.

  • Keep taking your daily prenatal vitamins.

    Just as when you were pregnant, you need enough vitamins and minerals for both yourself your baby. Prenatal vitamins are helpful, but you also need to eat a variety of healthy foods with lots of fresh fruits and vegetables.

  • Drink plenty of liquids each day.

    Your body needs plenty of liquid to produce breast milk. While breastfeeding, drink an extra 2 to 4 cups of water each day. Have a glass of water or herbal tea each time you sit down to breastfeed. If you feel thirsty, make sure you drink more.

  • Don't drink more than 2 cups a day of coffee, tea, cola, or other drinks that contain caffeine.

    Caffeine passes into your breast milk and can make your baby fussy.

  • It’s best to avoid alcohol while you are breastfeeding, just as you did during your pregnancy.
  • Alcohol passes into breast milk and can hurt your baby. It can also interfere with the release of milk from your breasts and slow the growth of your baby.
  • Do not smoke.

    The breakdown products from nicotine can pass to your baby in your milk. Smoking also may decrease your milk supply, increases the risk of sudden infant death syndrome (SIDS), make your baby fussier, and decrease the time your baby sleeps.

    If you cannot stop smoking, try to cut down. If you must smoke, do it after breastfeeding your baby. Above all, do not smoke in the car with your baby, in the same room as your baby, or in the house.

  • If you need to take any medicine, including nonprescription drugs, check with your healthcare provider, lactation consultant, or pharmacist.

    You need to make sure that the medicine is safe for babies who are breastfeeding.

  • Never use illegal or street drugs.

    Drug abuse by mothers is very dangerous to their babies who are breastfeeding. Even medical marijuana should not be used while you are breastfeeding.

  • Check with your healthcare provider before you start a program to lose weight.

    Your body uses the fat stored during pregnancy to make breast milk. This is why most breastfeeding mothers can lose several pounds each month. However, a strict weight-loss diet can decrease your milk supply. Talk with your healthcare provider about losing weight while you are breastfeeding.
